A hasta mudra is a gesture or positioning of the hands to channel and direct energy in the body. Mudras come from the over three thousand year old tradition of yoga originating in India. Hasta means “hand” in Sanskrit and mudra comes from the Sanskrit word “mud”, meaning to delight. A mudra is a “seal” as in sealing your connection with the Divine and sealing energy in the body.
